Syntax:

• LUTMERGE Rd3 BS3 Rs0 Rs1

Description:

The LUTMERGE operation yields a 128 bit result, whose high bank consists of the low bank of Rs1, and whose low bank consists of the low bank of Rs0:

High = [Rs1].L Low = [Rs0].L

This result is then written via Port3 of the register file to Rd3, according to the selected bank BS3.

Microcode Pattern:

Takes 4 cycles to execute.
    Example: LUTMERGE 0xC 3 0xA 0xB
